You're debugging at 11 PM. The API returns 200 OK. Your app is broken anyway. A field got renamed upstream. No alert. No log. Just a confused user. Fixzi is the developer data workspace that catches this before your users do. Validate, fix, compare and monitor JSON, XML and API responses — in one place. 🚨 Standout feature: API Contract Monitoring — automatically checks your endpoints and alerts you when response structure changes.
An API we depended on renamed one field.
Our checkout broke silently for 6 hours.
No alert. 200 status the whole time.
We found out from a customer email.
That frustration is why I built Fixzi.
It started as a JSON/XML toolkit, but evolved into something more useful —
👉 API contract monitoring that alerts you when responses change.
Would love your feedback 🙏
